Abstract (en)
[origin: US2020289992A1] An apparatus for producing nano-bubbles in a volume of liquid is described. The apparatus includes a motor having a rotatable shaft, an axially rotatable permeable member couplable to a gas inlet, and a rotatable tube support coupled to the rotatable shaft of the motor and having an inner cavity that houses the axially rotatable permeable member. When rotated, the axially rotatable permeable member is rotated so that the surface velocity of the rotatable permeable member simulates axial turbulent flow above the turbulent threshold in the liquid that allows the liquid to shear gas from the outer surface of the axially rotatable permeable member, thereby forming nano-bubbles in the liquid.
